Anyone have first hand at feeding yeast to corals, I can't find anything related to this. A local lfs does it and I don't understand why, would yeast be damaging to my small 20 gallon setup?

I've been feeding my tank yeast nightly for the ~1 month. I culture it and mix it with reef chili when I feed my tank. No negative issues with the yeast yet in my tank. I culture the yeast and feed it at the dosages documented in this article: http://onlinelibrary.wiley.com/doi/10.1002/ece3.3538/full. I think the guys at UniqueCorals also feeds their corals yeast as well.
Is the feeding you’re referring to? I couldn’t find where they mentioned dosages though?
Heterotrophic feeding
1.75 grams baker’s yeast, 14 grams sugar and 350 ml reverse osmosis water. This was freshly mixed three times each week in a conical flask, placed on a magnetic stirrer and incubated at 24 º C for 24 hrs prior to use. Solutions older than 72 hrs were discarded.
Hi, have you experienced using the yeast?Is the feeding you’re referring to? I couldn’t find where they mentioned dosages though?

Idk yet, depends on how it impacts phosphate and nitrate and whether tiny chunks dropped by an autofeeder will dissolve properly, if it has to be done by hand, probably every 3-7 daysThanks for sharing! How often do you plan to do it?
This article shows that Acropora and Pocillopora definitely capture Artemia Nuaplii as a food source.

Here’s a paper looking at optimal prey densities. It’s unfortunately behind a pay/request wall. Sometimes authors will send you the article if you contact them.

This study looked at five different dietary regimens on Millepora and Pocillopora. They found that at least for pocillopora, Artemia seemed to lead to higher growth rates. I wonder if the study was just too underpowered to detect statistically significant differences for Artemia treatment for millepora, as the graphs suggest that Artemia feeding yields more growth than filtered sea water. What’s interesting is how disappointed Reef Roids and the “novel, micro bound diet” performed.
Comparing the capacity of five different dietary treatments to optimise growth and nutritional composition in two scleractinian corals
Developing an optimal heterotrophic feeding regime has the potential to improve captive coral growth and health. This study evaluated the efficacy of three exogenous diets: Artemia nauplii (ART), a commercially available coral diet (Reef Roids) (RR), and a novel, micro-bound diet (ATF), against...journals.plos.org
Here’s an article that looked at Artemia feeding vs no feeding with Stylophora. Again the fed corals did better.
Here’s an article that looked at Artemia feeding vs not feeding in Pocillopora. Again, the fed corals did better.
Effects of feeding on the physiological performance of the stony coral Pocillopora acuta - Scientific Reports
Reef-building corals rely on both heterotrophy and endosymbiotic dinoflagellate autotrophy to meet their metabolic needs. Those looking to culture these organisms for scientific or industrial purposes must therefore consider both feeding regimes and the light environment. Herein the effects of...www.nature.com
In brief, the authors found the highest growth rates across three acropora species (Acropora loripes, Acropora millepora, and Acropora tenuis) with a Isochrysis galbana diet. Unfortunately they did not have an Artemia Nauplii condition in the experiment.
I think the second important take away from this study is that it's really hard to replicate food with a synthetic diet (think reef roids and misc).

I haven't fed yeast in ages; as time has progressed, my acros seem to just do best with good ol' elevated PO4, NO3 and fish poo. Maybe Elysics has an update.
Hopefully he will chime in. I run a little lighter fish load so I may give it a try.I haven't fed yeast in ages; as time has progressed, my acros seem to just do best with good ol' elevated PO4, NO3 and fish poo. Maybe Elysics has an update.
I think the yeast will be killed off by the salinity, the bacteria might eat it though yeah.Yeast, dry or wet, is a great food for bacteria to bloom. It will reduce Nitrates.
1 pound of dry yeast flushed down a toilet into a cesspool will eat the waste and clean the cesspool for the year.
